Hoderi no Mikoto (Umisachihiko)

Hoderi, known as Umisachihiko (Sea-Luck Prince), is the elder brother in the famous tale of the sea and mountain princes. A skilled fisherman, he became embroiled in conflict with his younger brother Hoori (Yamasachihiko) after Hoori lost Hoderi's prized fishhook. The resulting narrative leads Hoori to the undersea palace of the dragon god, where he obtains magical items that give him power over the tides.

Upon Hoori's return, Hoderi was forced to submit to his younger brother through the power of the tide-controlling jewels. His descendants are identified with the Hayato people of southern Kyushu, and a ritual performed at the imperial court reenacting Hoderi's submission was maintained for centuries.

Scholars interpret this myth as reflecting the political subjugation of the Hayato maritime peoples by the Yamato court, encoded in the language of divine sibling rivalry.
